Significantly louder than the HX MXM4's they replaced. Noise starts right at 40mph and gets significantly louder at highway speeds. Likely going to swap them out for another brand as this is the only Michelin tire that fits 245/50/R17. Tire handles great but I just can't deal with the noise.

I originally bought the Michelin Pilot Sport A/S 3+ with a wheel and tire package in 2016. Those tires were very impressive and held up well. When I had to get new tires, the Pilot Sport A/S 4's were a no-brainer. I've had a while to give them a full and honest review. In dry conditions these tires perform just as well as any summer tire on the market. There is no lack of grip in cornering and little to no road noise depending on the condition of the road. In wet rain conditions these tires grip the road very well and keep the car grounded through corners. In snow conditions the tires do pretty well, depending how much snow. I have had some traction issues in over two inches of new snow. Obviously in these conditions, you use your best judgement and use an abundance of caution and maybe even opt for a winter tire if conditions call for it. Overall they perform well in cold conditions up to -10 below. I've never had a traction issue on cold dry roadways using these tires. Ice and snow may bring a little bit of traction issues from a dead stop, but once you are up to speed you will have enough grip to make it home. After close to two years of driving with roughy 30-45k highway miles (and not always following the reccomended tire rotation intervals) all tires are at a 7/32 tread depth and still have plenty of life left. Someone may look at the overall price point and opt for a cheaper tire option, I wouldn't call it the most "economical" option. In terms of "you get what you pay for" these are worth every penny. There's a reason you see plenty of performance manufacturers putting Pilot Sports on from the factory. It's not a gimmick. These tires will last much longer than other brands, and will continue to deliver the performance and safety you expect from a brand like Michelin.

I put these tires on my 2017 VW GTI SE as a replacement for the Pilot Sport AS3+ that I had on there for the past couple of years. I loved the AS3+, the car had really great grip and it handled like it was on rails. The steering feel and turn in was very sharp and there was almost no lean in corners. The AS4 has somewhat better ride quality than the AS3+ and great grip but the sharp cornering feel and confidence in handling curves isn't there as with the AS4. It feels more like a grand touring tire with a grippier compound whereas the AS3+ feels more like a performance tire with the ability to be used in cold weather and light snow.

I’ve previously owned the AS3 and AS3+. These new AS4 are noticeable better. It handles and grips just as good as previous models. The improvement is in the noise and comfort level. Noise being more muted, meaning in a more comfortable ride. It’s an early assessment but hope the durability and longevity will be impressive. We will see.

Big fan of Michelin Pilot Sport AS 3+. Have them on two family cars. Just installed the new Pilot Sport AS 4 on my daughter's 2020 Honda Civic LX. Replaced the OE tires. It's a entirely different driving experience. Love these tires. Fantastic Product

Randomly worn in a section of the tire between the centre and outside edge of the tire. Only had them on my X5 for 25,000 km Always been a fan of Michelin but this is the last set I buy. I don’t even want to attempt a warranty claim because they still aren’t worth it.

I no longer engage in terribly spirited driving (its been 25 years since racing school), but I still appreciate a superior sticky tire. I have also gained a fondness for a quiet , smooth ride, which you normally don't expect with a performance tire. I was therefore pleasantly surprised at how much these tires delivered all these qualities with so few of the usual compromises. For my purposes, this was an excellent choice, with much more grip than the OEM tires, and equal smoothness and very little more road noise. Unless you think you want a super stickey tire ( and are willing to pay the price in dollars and discomfort), I recommend the A/S 4. It looks like the new standard for an all season performance tire.

I replaced the original tires on my 2011 Z06. I noticed an immediate smoother ride and much less noise in the car. Straight line acceleration is very similar even with the heads and cam mods. I am not easy on the car and drive aggressively when I take it out. I was considering a higher performance Michelin tire but am pleased with the All Season 4. How long they last is TBD.

Great tires but they don't last. I'm at 46000km and they are down to the wear bars and not even three years old. Like I said, no other issues except for tread life. I would give it five stars if lasted 80000km or even 70000km . Driven on a Lincoln MKX with no aggressive driving.

I have 2 sets of these tires, for my 1993 Corvette ZR-1 and my 2015 Challenger 392. Excellent grip in all weather conditions that I drive in (I rarely see snow, but frequent heavy rain and temps below summer tire ratings) as well as quiet and comfortable.
